    Determination of organic acids by GC-FID: on cartridge derivatization by silylating reagent (MTBSTFA)

    PENNINGTON A.S.C.; PLUNKETT S.
    Enthalpy Analytical, LLC, Durham, NC, U.S.A.
    Organic acids are compounds that, when used in electronic nicotine delivery systems (ENDS) devices and e-liquids, can alter the perception and uptake of nicotine by the consumer. Traditional means of analysis by suppressed IC (Ion Chromatography) can...

    Development and characterization of an alternative rotary-like ENDS collection method for in vitro toxicology testing

    COFFA B.G.; KOSACHEVSKY P.; SMITH M.; McFADDEN L.; SOVICK C.; SMITH J.; KALLAM B.; PRESS E.; PICKELL T.; PATEL N.; KUMARI A.; SCIAN M.
    Enthalpy Analytical, LLC, Richmond, VA, U.S.A.
    Testing of ENDS aerosol collected condensate in the in vitro toxicology assays is limited by OECD guidelines for the maximum allowable solvent levels that can be tested, as well as the final concentration of the generated aerosol condensate. The...

    Market survey of modern oral nicotine products: determination of select HPHCs and comparison to traditional smokeless tobacco products

    JABLONSKI J.J.; CHEETHAM A.; MARTIN A.M.
    Enthalpy Analytical, LLC, Richmond, VA, U.S.A.
    In an effort to combat the risks associated with traditional tobacco products, tobacco science and product innovation has been redirected towards providing the consumer with products that may limit their potential exposure to harmful or potentially...

    Effect of pH and storage temperature on e-liquid metal concentrations

    COLLINS D.; HOCHSTETLER S.; CRABTREE R.; HEIGTER D.; NGO V.
    Enthalpy Analytical, LLC, Richmond, VA, U.S.A.
    E-liquids are available in a variety of nicotine formats and concentrations. Nicotine formats can be either nicotine freebase or nicotine salt. Nicotine salt is formed by combining nicotine with an organic acid. The pH of these nicotine salts ranges...

    Analysis and differentiation of tobacco-derived and synthetic nicotine samples

    CAMPBELL P.(1); CHEETHAM A.(2); COFFA B.(2); HILLDRUP J.(2); GILLILAND S.(1); PLUNKETT S.(1,2)
    (1) Consilium, Richmond, VA, USA ; (2) Enthalpy Analytical, Richmond, VA, USA
    There is significant regulatory and economic need to distinguish between tobacco-derived (TDN) and synthetic (SynNic) in commercial products. While products that contain TDN are regulated by FDA, those with SynNic are currently exempt from regulatory...

    The synthetic nicotine loophole: regulatory issues and technical challenges

    COFFA B.G.(1); GILLILAND S.(2); BURD K.(3); SPROWL E.(4); CAMPBELL P.(2); PLUNKETT S.(1,2)
    (1) Enthalpy Analytical, LLC, Henrico, VA, USA; (2) Consilium Sciences, Richmond, VA, USA; (3) North America Nicotine, Rocklin, CA, USA; (4) Pyxus International, Morrisville, NC, USA
    A significant scientific, regulatory, and economic need exists to distinguish tobacco-derived nicotine (TDN) from synthetic nicotine (SynNic) to assess its use in commercial products. Products containing TDN are regulated by FDA; however those with...

    Determination of organic acids by GC-FID: on cartridge derivatization by silylating reagent (MTBSTFA)

    PENNINGTON A.
    Enthalpy Analytical, Durham, NC, USA
    Organic acids are compounds that, when used in ENDS devices and e-liquids, can alter the perception and uptake of nicotine by the consumer. Traditional means of analysis by suppressed IC (Ion Chromatography) can lead to long runtimes in excess of 70...
